the class EncryptionUtils method resolveKeyId.

 * @param value the source value to resolve the keyId for. Must not be {@literal null}.
 * @param evaluationContext a {@link Supplier} used to provide the {@link EvaluationContext} in case an
 *          {@link Expression} is {@link ExpressionUtils#detectExpression(String) detected}.
 * @return can be {@literal null}.
 * @throws IllegalArgumentException if one of the required arguments is {@literal null}.
